3. Specifications guaranteed by design & characterization.
4. Specifications measured as an instantaneous quantity NOT as a time-averaged quantity.
5. STBY is designed to be driven by an open-collector device. The input is internally pulled up with a 600 kΩ resistor.
6. The package thermal impedance is calculated in accordance with JESD 51.
7. For an output voltage, Vout, other than 460V, the threshold scales by a factor of Vout/460
